POLYGRAN® Roller Compactor


Leaders in Roller Compactors

The POLYGRAN® roller compactor is the entry level Gerteis® roller compactor. With many of the unique roller compactor technologies of the PACTOR® range included, the POLYGRAN® offers outstanding value for money for such a sophisticated roller compactor that will deliver excellent dry granulation results. With a capacity of 500g upto 200 kg per hour, the POLYGRAN® is suitable for both development and production environments.

POLYGRAN® roller compactor features

  • Simple but accurate feed system to the rollers to ensure consistent dosing of powder to the rollers.
  • Angled compaction rollers to allow feed consistency, constant ribbon density and to minimise temperature gain.
  • Free floating gap design and in-process force control producing a constant density ribbon
  • Large rollers diameters to produce a longer dwell time in the nip area.
  • Superior punch & die roller design to provide a constant density over the ribbon width and to virtually eliminate fines (no recirculation required!)
  • Simple but effective granulating oscillating mill with adjustable screen clearance, to produce a consistent and controllable particle size distribution.
  • Full instrumentation with critical quality process parameter data-acquisition.
  • Full machine calibration.
  • Reduced number of interchangeable parts for easy disassembly and reassembly.
